Interaction data: Firefox sends data about your interactions with Firefox to us (such as number of open tabs and windows number of webpages visited number and type of installed Firefox Add-ons and session length) and Firefox features offered by Mozilla or our partners (such as interaction with Firefox search features and search partner referrals). Firefox by default shares data to: Improve performance and stability for users everywhere We also adhere to the practices outlined in the Mozilla privacy policy for how we receive, handle and share information we collect from Firefox.
In this Privacy Notice, we explain what data Firefox shares and point you to settings to share even less. You can read more about this data below, including how to disable data sharing and search recommendations. This means that the software can be viewed and examined by the public. Cliqz does not build browsing profiles for identifiable individual users with this data and, like Firefox, Cliqz is open source. If you are using a version of Firefox with Cliqz search recommendations, Cliqz will receive data in order to carry out your requests, as well as anonymized browsing data used to create the search engine index. Cliqz shows results and websites recommendations directly in the Firefox URL bar.

One of our technology partners is Cliqz GmbH, a German company owned by Hubert Burda Media and Mozilla, the maker of Firefox. We strive to collect only what we need to improve our products for everyone and work with partners who share a commitment to protecting our users. That’s why we build Firefox, and all our products, to give you greater control over the information you share online and the information you share with us. At Mozilla, we believe that privacy is fundamental to a healthy internet.
